Application filed July 14, 1910. Serial No. 572,000.

To all whom it may concern.-

Be it known that l, JOSIAH R. MCCoY, citizen of the United States, residing at Marshallt-own, in the county of Marshall and State of Iowa, have invented certain new and useful Improvements in Earth- Uhipping h'laohines, of which the following is a specification.

This invention relates to earth chipping machines and has for its object the pr0vision' of a machine of simple and durable construction, adapted to be advanced over a hillside or a level stretch of ground for the purpose of loosening the tillahle soil so as to catch and retain the rain fail, and thus enrich the earth and at the same time prevent the surface soil from being washed away.

A further object is to provide an earth (-hipning machine including a wheeled truck hai ing a cutter mounted for rotation on the rear end thereof and adapted to pass through the soil and loosen the latter without throwing the soil on either side of said cutter.

A further object is to provide improved moans vtor raising and lowering the cutter, and means for looking mid cutter in differ ent positions of adjus ment.

A, still further ohjoct f the invention is generally to improve this class of machines so as to inert-rise their utility, durability and efficiency.

Further ohjm-ts and admntages will appear in the l'ollowing dvsrription. it being understood that various ('hanges in form, proportions and minor detail: f construetion may he resorted to iihin the scope ot the appended clain'is.

For a full uiulerstamiii ot' the invenrt-l't-rvnoe is to be had to the Following den iption and am oompanying drawings. in \\'ltl(. lI

Thus it i will he e-en that by depressingthe'reduced end of the pawl 63, the tooth 64 will be disl engaged from the ratchet wheel, so that by oscillating the lever 59, the sprocket wheels 51' will be rotated and through the medium l of the chains 57 elevate the chipping device I in regniaie the depth of cutting thereof, the l pawl'm, by engagement with the ratchet wheel 58, serving in lock the frame and 1 i-niier in ailinsteil position.

It will here-he liuiili that; the r-on'struction of the cutter shown in Fig. i of the drawing, is such that the blades thereof pass through the soil without throwing the latter on either side ofthe cutter, so that the soil tlmstreated, will be ill-condition to receive \and retain the rain fall, which latter h'as a tendency to rot the soil and thus dispense l with the use of fertilizer, while at the same time causing the soil to be thoroughly irrigated.

wheel 58 and jonrnaleii on the Shaft on the v 5, thus I Having thus described the invention, what is claimed as new is:

1. A machine of the class described including a wheeled truck, a driving shaft, a tilting frame having one end thereof pivotally mounted on the driving shaft, a cutter mounted for rotation on said frame at the free end thereof, a motor 0 eratively connected with said driving shaf t a crank shaft journaled on the truck and provided with crank arms engaging the opposite sides of the frame, a stub shaft disposed above the crank shaft, flexible connections between the stub shaftand crank arms, a ratchetwheel secured to the crank shaft, a lever pivotally mounted on said stub shaft and adapted to engage the ratchet wheel for elevating the frame, a pawl engaging the ratchet wheel for holding the frame in adjusted position, and means for transmitting motlon from the driving shaft to the cutter.

2. A machine of the class described including a wheeled truck, a driving shaft, a frame pivotally mounted on the opposite ends of the driving shaft and including side bars spaced from the adjacent sides of the truck, a cutter mounted for rotation on the free end of said frame, a crank shaft having its intermediate portion journaled on the truck and its opposite ends provided with crank arms journaled in the side bars of the frame, a stub shaft disposed above the crank shaft, s rocket wheels secured to the opposite en s of the stub shaft, sprocket chains forming a connection between the sprocket wheels and crank arms, means for rotating the stub shaft to effect the vertical adjustment of the frame, means for holding the frame in adjusted position, a motor mounted on the truck, a connection between the motor and driving shaft, and aconnection between said driving shaft and cutter for transmitting motion from one to the other.

In testimony whereof, I afiix my signature in presence of two witnesses.
